T0 all whom t may concern:

Be it known that we, JOSEPH SIMPSON and ALDnN A. LUKE, citizens of theUnited States, residing at Spokane, in the county Of Spokane, State ofWashington, have invented certain new and useful Improvements in BrushHeads; and we do hereby declare the following to be a full, clear, andexact description Of the invention, such as will enable Others skilledin the art to which it appertains to make and use the same.

This invention relates to brush heads, and more particularly to lonedesigned for use for sweeping streets Or stables.

The invention has for its object to so con-y struct a head of this typethat the broom can be readily removed and replaced by a new one whenworn out.

A further object of theinvention is to provide a broom head with ascraper which can be conveniently used upon reversing the brush.

With these and other objects in view, this invention resides in thenovel features of construction, formation, combination and arrangementof parts to be hereinafter more fully described, claimed and illustratedin the accompanying drawing, in which Figure l is a perspective viewy Ofthe device. Fig. 2 is a sectional view on line 2-2 of Fig. 1. Fig. 3 isa perspective view of the clamping bar.

The head 1 consists of a channel bar 2, the opposite ends 3 Of'which are,bent inwardly, the purpose of which will appear later. Riveted to theouter surface of the bar 2 is a. scraper 4 which extends the entirelength of the bar 2 and is arranged at an inclination with respectthereto. The clamping bar 5 is also formed from channel iron, and hasits opposite ends so cut as to provide reduced, extensions 6, which areadapted yto Vengage the channels of the bent ends of the bar 2, and whenthus engaged vertical movement of the clamping bar 5in respect tothe bar2Q is prevented. Fixed to the central portion Of the clamping bar 5, andupon the outer surface thereof is a shank 7, and to which is secured thehandle 8.

The brush 9 may be formed from material suitable for rough usage, suchas cleaning streets, stables or yards.

The upper end of the brush material is placed between the bar 2 andclamping bar 5, with the clamping bolts 10 passing through the brush andengaging the bar 2 and clamping bar 5, but when the clamping nuts 11 aredriven home the bar 5 will be moved to ward the bar 2, thus firmlyclamping the brush at points 12 and 13 so that vertical movement of thebrush is positively prevented, lateral movement of the same beingprevented by the bolts 10 and bent ends 3.

By providing the scraper 4 it is obvious that upon reversing the brushthe same can be used conveniently when necessary.

What is claimed is A brush head including a Ushaped member formed ofchannel iron with the inner sides of the flanges converging in thedirection of the web wherebv the resultant channel is constricted at thebottom, a clamp member formed of channel iron and being substantiallystraight from end to end and being equipped on the end edges withtapered lugs adapted to fit slidably and snugly in the channels of thelegs of said U-shaped member, brush material inserted between saidmembers, and clamp bolts passed through the webs of both members andserving to draw the members toward each other with a resultant bindingof said brush material therebetween.

In -testimony whereof, we afx our signatures in the presence of twowitnesses.
